How to get overspray off tires

Take rim off car, sand blast the rim to bare metal front and back and during that process, lightly do the tire at the same time. Then mask off the tire to rim nicely so paint does not get on the tire, wipe a judicious amount of lacquer thinner on the rim to degrease it and paint the rims up right.

If you dont have sand blaster then take them to someone who will do it for you. Bead blasting will work and soda might as well but soda probably wont get the rim metal properly profiled for paint to stick nicely.
